I find the cause of failure in case 340

["Zhang, Sonic" <sonic.zhang@xxxxxxxxx>]

Hi,

        The following lines in case 340 fail to work. My environment is
redhat 7.3 and pcp-2.3.0-8.

        list2=`_all_hostnames $other2`

        Variant "other2" is a remove host.
        Function "_all_hostnames()" in file common.check fails to find out
all hostnames of the given remove host. It output nothing to variant
"list2", which cause incorrect configure in dummy file pmcd.conf.

        Could you please check function "_all_hostnames()"?

        Thanks.
